Slashdot posted a review of Perl & XML. This book is number one on my list of books to get. The reviewer made some negative comments about the book index and indicated many first edition book indexes aren't very good. [This comment did not impact my desire to get this book soon.]
I was just curious what the indexing process is at O'Reilly. I know Don Libes, author of the Expect book, insisted that his book should have a thorough index. It's so thorough, in fact, that even silly words made in off-hand comments are found so you can find the discussion that they were in. (Strangely useful.) The author doesn't produce the index, do they? Is there an indexing staff? I like good indexes (ever since the Expect book), so you can put down my vote for beefing up the indexing procedures.
All in all, the book seems to be targeted at me according to the review: experienced Perl programmer, understands OO, not afraid of online docs, needs to know what XML is and what to do with it.
